iOS 8 Document Provider extension

Extensions In General

So what are these new extensions that we all keep hearing about? In the last WWDC 2014, one of the more interesting subjects was the App Extensions, which is basically a new tool that allows different 3rd party apps to communicate with each other, or more correctly, allows them to have a controlled shared environment in order to increase the file accessibility between apps in iPhones, iPads and all the iOS system devices. Us developers can now create different extensions in our app to send, open or edit different kind of file like images, docs, pdf’s etc. A „shared folder“ for different uses and file sharing.

In The Past

Up until now, the only ways to transfer a file for example from one app to another was to find your file through a provider’s app and click the “Open in” option to send a copy of the file to another app, that can handle your file once it gets it.
